Layout and Planning
Layout and Planning
Proper layout prevents small cuts, minimizes waste, and ensures symmetry. For large format tile, layout is critical because the tile's size magnifies errors. Start by finding the center of the room and snapping chalk lines. For LFT, a common rule is to avoid cuts smaller than half a tile width at walls; adjust the layout to balance cuts. Consider the direction of the tile's grain or pattern, and plan for expansion joints at perimeters and between rooms. Account for the grout joint width: larger tile often uses a minimum 1/8-inch joint (or per manufacturer). Dry-lay tile to visualize the layout and check for lippage. Traps: starting with a full tile at the most visible wall without checking the opposite wall; forgetting to account for the thickness of thinset and substrate; and not planning for movement joints. Worked example: In a 10-foot by 12-foot room with 24x24 tile, the center lines divide the room into four quadrants. If you start with a full tile at the center, the cuts at the walls will be about 12 inches (half tile), which is acceptable. If the room were 11 feet, the cuts would be 6 inches, which is too small; shift the layout by half a tile to get 18-inch cuts.
